When a French commercial lease (bail commercial) comes up for renewal, a landlord who wants to escape the statutory rent cap often relies on changes in the area: new transport links, new retail brands, a growing population. The tenant answers that its business has not benefited. The reported decision of the Third Civil Chamber of the Cour de cassation (the French supreme court for civil and commercial matters) of 18 September 2025 settles the point: a material change in local commercial factors (facteurs locaux de commercialité) justifies uncapping the rent (déplafonnement, the release of the renewal rent from the statutory cap) if it is capable of favouring the activity carried on, without proof of its actual effect on the business. The evidence therefore concerns the premises’ surroundings, not the operator’s accounts.
The facts
A company selling and displaying light fittings, tenant of commercial premises, applies for renewal of its lease. The landlord accepts the principle but asks for the rent to be raised to a figure higher than the one offered by the tenant, and sues to have the renewed lease’s rent set by the court. During the proceedings, safeguard proceedings (procédure de sauvegarde, a court-supervised restructuring) are opened in favour of the tenant; a safeguard plan is then adopted and a plan supervisor (commissaire à l’exécution du plan) is appointed.
The case had already been through one cassation (Cass. 3e civ., 17 September 2020, appeal no. 19-19.433). Rehearing the case on referral after that cassation, the Paris Court of Appeal, on 25 January 2024, set the rent of the renewed lease at rental value, dismissed the claim for repayment of the excess rent paid since 1 July 2014, set the new security deposit and entered in the tenant’s liabilities the difference between the old and the new deposit.
The tenant and the plan supervisor appealed to the Cour de cassation. They criticised the lower courts for holding it sufficient that the material change in local commercial factors be “likely to have an effect on the commercial activity carried on by the tenant” (translated from the French), whereas, in their view, “the law requires that the actual effect be established”.
The decision
The Cour de cassation dismissed the appeal (Cass. 3e civ., 18 September 2025, appeal no. 24-13.288, reported). It held that it follows from articles L. 145-34 and R. 145-6 of the French Commercial Code that “a material change in local commercial factors constitutes a ground for uncapping the rent of the renewed lease if it is likely to have a favourable effect on the commercial activity actually carried on by the tenant, regardless of its actual and real effect on the business operated in the premises”. The ground of appeal, “which assumes the opposite”, therefore failed.
The articles cited by the Court set the framework. Article L. 145-34 lifts the cap where there is a material change in the elements listed at 1° to 4° of article L. 145-33, which include local commercial factors; article R. 145-6 links those factors to the interest that, for the business concerned, lies in the size of the town, the district or the street, the spread of activities, transport links, and the particular appeal or constraints of the location.
The rule has three elements. The change must be material. Its effect must be favourable to the activity “actually carried on” by the tenant, that is, to the business as it is operated in the premises. Finally, that effect need not have materialised: it is enough that the change is capable of favouring that activity.
The decision follows on from the ruling of 13 October 2021, which already required the material change in local factors to have a favourable effect on the activity carried on in the let premises, in a case about a terrace extended onto public land (discussed in this article). The appeal relied on a similar wording to demand an established effect; the more recent 2025 decision makes clear that the change’s capacity to favour the activity is enough.
What this changes for valuation
The evidence concerns the surroundings of the premises, not turnover. The landlord does not have to show that the tenant’s sales have risen, and the tenant does not defeat the claim by producing flat or falling accounts. The report documents the change during the expired lease: transport links, footfall, the district’s population, new retail brands, public amenities, parking conditions. Each item is dated and sourced (transport operator data, population statistics, planning permissions, footfall counts).
The link with the activity carried on must still be shown. The change must be capable of favouring the business actually operated, not any business. For instance, a new transport stop matters first to a business that lives on passing trade; for a showroom, car access, parking or the arrival of complementary retailers may count for more. The decision does not say which factors had changed in this case. The report explains why the change is useful to the activity concerned: target customers, means of access, neighbouring shops. The Orléans Court of Appeal already reasoned this way in 2019, assessing the interest of the change in the street’s clientele for the business concerned independently of the tenant’s turnover (see this article).
Materiality must still be measured. The decision concerns the effect of the change, not its scale. The valuer quantifies the variation over the term of the expired lease: use of a transport line, residents or jobs, occupied commercial units in the street.
Each criterion has its own rules. Works decided on and carried out by the tenant, not claimed to be improvements, which materially altered the characteristics of the let premises during the expired lease, justify uncapping on their own, without any inquiry into a favourable effect on the activity (ruling of 9 September 2021). A new statutory obligation placed on the landlord during the expired lease falls under the respective obligations of the parties (another reported ruling of 2025). The report assigns each change to its own criterion and applies only that criterion’s condition.
Uncapping does not set the rent. Market rental value still has to be established (Charte de l’expertise en évaluation immobilière, the French property valuation charter, 6th edition, November 2025, Title III, § 1.4; EVS 1 of the European Valuation Standards 2025) from rent references reduced to a weighted floor area. For leases entered into or renewed since 1 September 2014, the increase resulting from a material change is in principle limited, each year, to 10 % of the rent paid in the previous year (article L. 145-34, last paragraph). The 2025 decision does not address that point.
What the valuer takes from it
- A material change in local commercial factors uncaps the rent if it is capable of favouring the activity carried on; its actual effect on the business need not be proven.
- The report dates and sources the change in the surroundings during the expired lease and explains why it is of interest to the business actually operated.
- Flat or falling accounts do not rule out uncapping; the change must still be shown to be material.
- Once the principle is settled, rental value is demonstrated with rent references.
